On a whim I opened an incognito window and was able to login right away. I went back to the normal browser and cleared the cache & cookies. I am now able to login on my laptop. I'll try clearing the cache on the Mac when I get a chance to access it.
I cleared the cache and cookies "from the beginning of time" on the Mac, and now it also can login. I'm not sure what caused the initial failure, but at least it's fixed for me now on both machines.
